don't hold that against your friend man. i got my friend and i busted when i was a newb smoker and i regret it all the time. i packed a gravity bong bowl way too big for my level at that time, his mom was right upstairs. i started coughin before i finished the hit and blew smoke through his house cause i missed the window. she smelled it and came down. shit happens i guess.

chances are that your friend feels really bad about what happened, probably a lot worse than you feel about it. so yeah, a joke or two maybe in a little while from now, but give the kid a break. my friend would rub it in all the time, finally one day i couldn't take it anymore and i just hit the kid... a few times. felt bad about it after but he wouldn't give up.

also, i don't know too much about legal information but there is a legal forum right near here, check that out.
